Configuration problem running dv8 showcase

[rnkazman]

I received this error when running the dv8_showcase:

Error in parse_gitlog(perceval_path, git_repo_path) :
Unable to generate git log from this repository. Perhaps the path specified was incorrect or the repository has no commits?

I checked the value of perceval_path and it is correct.

The git_repo_path is: "../../rawdata/pdfbox/git_repo/.git"

The showcase is being run in ~/Documents/GitHub/kaiaulu/kaiaulu
so the git_repo_path will turn into ~/Documents/GitHub/rawdata/pdfbox/git_repo/.git

But I was advised to create the rawdata folder within ~/Documents/GitHub/kaiaulu, which is what I did. The folder is:
/Users/rnkazman/Documents/GitHub/kaiaulu/rawdata

Clearly these do not match. What is the prefered solution?

Not sure I follow the question. Are you asking why ../../ when it is ../?

If so, this is a common point of confusion but it has less to do with Kaiaulu and more how it works when you are using the RStudio IDE.

When you press play on the code block, you are executing the .Rmd file. That is on vignettes, hence ../../. However, if you copy and paste the code to the console, then you are running from whatever directory is specified, which generally is kaiaulu/kaiaulu.

Or are you saying the config specifies to be in ~/Documents?

I'm not sure I follow the answer. :-)

I believe that I followed the folder conventions (that you helped me to organize), and I have not changed any path or code in dv8_showcase.Rmd, so why am I getting this error? The error indicates a path problem. Hence my confusion.

I am attempting to execute these lines in the showcase:

#git_repo_path <- "~/Downloads/testing-cochange/.git"
project_git <- parse_gitlog(perceval_path,git_repo_path)
project_git <- project_git  %>%
  filter_by_file_extension(file_extensions,"file_pathname")  %>% 
  filter_by_filepath_substring(substring_filepath,"file_pathname") %>% 
  filter_by_commit_size(commit_size = filter_commit_size)

kable(head(project_git))

and I get this error:

Error in parse_gitlog(perceval_path, git_repo_path) :
Unable to generate git log from this repository. Perhaps the path specified was incorrect or the repository has no commits?

Looking closely:

The git_repo_path is: "../../rawdata/pdfbox/git_repo/.git"

Try to use instead: "../../rawdata/pdfbox/git_repo/pdfbox/.git"

Notice I added a /pdfbox/ before the .git. When you git clone a project, you download both its source code, i.e. /pdfbox/ and the git log, i.e. /pdfbox/.git inside of it. To double check the path, I suggest you go via terminal using cd inside the .git folder, and then type pwd.

This is also what is used in Calculator:

kaiaulu/conf/calculator.yml

Line 39 in ac522b6

log: ../../rawdata/Calculator/git_repo/Calculator/.git

I would in fact, recommend you try to run the notebook on Calculator first before trying to make your own on pdfbox just to get used to the path organization.
